Abstract: Disclosed is an anhydride-free insulation system for current-carrying construction parts of an electric engine which comprises: (A) a mica paper or mica tape for wrapping parts of said electric engine that are potentially current-carrying during operation of the engine, which mica paper or mica tape is impregnable via vacuum pressure impregnation with a thermally curable epoxy resin formulation and comprises one or more thermally activatable sulfonium salt initiators for the homopolymerisation of the epoxy resins present in said said thermally curable epoxy resin formulation or a mixture thereof in an amount sufficient to homopolymerize the epoxy resin taken up by the mica paper or mica tape and the construction part of the engine during the vacuum pressure impregnation step; (B) a thermally curable bath formulation for the vacuum pressure impregnation comprising (i) a polyglycidyl ether or a mixture thereof, and (ii) a cycloaliphatic epoxy resin comprising at least two epoxy groups, which are fused to a cy

Abstract: The invention relates to the use of a polymer composite (1, 1?), comprising a backing material (3, 3?), selected from the group made up of polyethylene terephthalate (PET), polyethylene naphthenate (PEN) and ethylene-tetrafluoroethylene copolymer (ETFE), and layers of nylon 12 (2, 2?, 4, 4?) adjacent to the backing material on both sides, for producing photovoltaic modules.

Abstract: Polyamide as an encapsulating material for the production of photovoltaic modules.

Abstract: A method for producing photoactive layers, and components, such as solar cells, including the layers. According to the invention, the photoactive layers are produced by forming a non-semiconducting layer from precursor material including at least one metal compound and a salt-like and/or organic reactant on a substrate by printing or blade coating, the layer being exposed to temperatures of less than 300° C., wherein a semiconducting, photoactive layer is formed from the non-semiconducting layer by thermal conversion of the precursor material.

Abstract: The invention relates to a method for producing a layer containing inorganic semiconductor particles. According to the invention, the layer containing inorganic semiconductor particles is formed in situ from metal salts and/or metal compounds and a salt-type or organic reactant within a semiconducting organic matrix. The layers containing inorganic semiconductor particles and produced according to the invention enable a simple and cost-effective production process for photovoltaic elements, such as solar cells or photodetectors.

Abstract: A process produces weather-resistant laminates (1, 1?) for the encapsulation of solar cell systems (7). The process includes at least one weather-resistant plastic layer (2, 2?) being applied on a carrier material (4, 4?). The coating process shows the advantage that the relatively expensive starting products, which usually are used in the form of films, can be reduced in their thickness and in amounts thereof used. Owing to the controllable adjustment of the layer thickness of the weather-resistant layer (2, 2?), a considerable number of applications of the laminates that are produced, in particular in connection with the finished photovoltaic modules, are provided. These applications range from small energy units for emergency telephones or campers to large-area roof and facade systems and also large units and solar power plants.
